NASA has set a provisional launch date of July 2028 for its Dragonfly mission, meant to discover Saturn’s largest moon Titan, with budgetary uncertainty cited as the rationale for the challenge’s one-year delay.
The Dragonfly group can now transfer ahead with the following stage of improvement — Section C — for the car-sized, nuclear-powered rotorcraft drone that can fly above and land on the sands of Titan, a world planetary scientists consider is wealthy in natural molecules.
“The Dragonfly group has efficiently overcome a variety of technical and programmatic challenges on this daring endeavor to collect new science on Titan,” NASA Science Mission Directorate affiliate administrator Nicola Fox mentioned in a press release. “I’m happy with this group and their capacity to maintain all points of the mission transferring.”

At NASA’s Outer Planets Evaluation Group (OPAG) assembly on Nov. 28, the director of the company’s planetary science division, Lori Glaze, revealed the rationale for the launch delay — initially set to go to Titan in 2027. She mentioned that formal affirmation of Dragonfly and the official costing and scheduling of the mission by NASA’s Company Program Administration Council (APMC) had been postponed as a result of uncertainty about how a lot cash can be accessible for the challenge.
“Due to these extremely massive uncertainties in Monetary Yr 2024 and Monetary Yr 2025 funding and budgets, the choice was made on the APMC to postpone the official affirmation,” Glaze mentioned on the assembly.
She added that Dragonfly can be taken again to the APMC in spring 2024 after NASA’s Monetary Yr 2025 price range proposal.
The group will replan the mission upon request, and when any essential restructuring has been accomplished and reviewed, NASA will formally assess the mission’s launch readiness date in mid-2024. This implies some parts of Dragonfly’s last mission design and fabrication might be delayed whereas others proceed.
Up to now, Dragonfly is the one NASA mission scheduled to go to the floor of an ocean moon. As soon as at Titan, the drone will seek for circumstances that would suggest habitability. Dragonfly will even examine how far any doable prebiotic chemistry has progressed on the moon of Saturn and even hunt for indicators of water or hydrocarbon-based life that exist already there.
Along with touring additional throughout an alien world than every other planetary rover has, the 4 dual-bladed rotorcraft will even land on Saturn’s floor in several areas, gathering samples to find out the composition of floor supplies below various geological circumstances.
The investigation of Titan is of excessive precedence for planetary scientists as a result of, along with being an ocean world, it’s the solely photo voltaic system moon identified to own a thick environment and an Earth-like hydrological cycle of methane clouds, rain and liquid flowing throughout its floor and filling lakes and seas. This, and the potential presence of ample advanced natural supplies frozen into the moon‘s icy floor, boosts the potential for habitability on Titan.
Dragonfly, which might be constructed and operated by Johns Hopkins Utilized Physics Laboratory (APL) in Laurel, Maryland, is constructed to conduct this investigation utilizing its geared up cameras, sensors and samplers.
“Dragonfly is such a daring endeavor, like nothing that has ever been executed earlier than,” Dragonfly principal investigator Elizabeth Turtle mentioned. “I am impressed by the best way our group has repeatedly overcome challenges by working collectively and considering exterior the field.”
A number of Dragonfly elements, together with its management and navigation techniques, have already been examined over the deserts of California — chosen for its resemblance to the sand dunes of Titan — in addition to in wind tunnels at NASA’s Langley Analysis Middle. A full-scale mannequin has additionally been examined in Johns Hopkins APL’s huge Titan Chamber — which simulates the frigid temperatures and atmospheric pressures of Titan’s methane-rich atmosphere.
“We have demonstrated that we’re prepared for the following steps on the trail to Titan, and we’ll maintain transferring ahead with the identical curiosity and creativity which have introduced Dragonfly up to now,” Turtle concluded.
